Hi, I am working on the imxmp-verdin platform. One of the quirks with this particular som is that it uses an internal pcie_phy clock instead
of
an external one like most imx8mp boards do. To get this working on mainline linux, the way clocks are defined for
the
pcie_phy is `clocks = <&hsio_blk_ctrl>;` However this causes u-boot to completely fail to boot with this error `Device tree error at node '__symbols__'` .
That looks like a strange error was found when trying to read the compatible string from the node. It wasn't -FDT_ERR_NOTFOUND. See lists_bind_fdt().
Perhaps we need to ignore the __symbols__ node?
For now the fix seems to be `clocks = <&hsio_blk_ctrl 0>;` This let's uboot proceed and pcie is working under linux as well.
My end goal is to boot a generic arm image over pcie nvme, I don't
know if
this would be possible but atleast a compatible device tree would be a
good
starting point.
Thanks.
Regards, Simon
